Visual Modulation Of Resting State Α Oscillations, Kelly Webster, Tony Ro
Visual Modulation Of Resting State Α Oscillations, Kelly Webster, Tony Ro
Publications and Research
Once thought to simply reflect passive cortical idling, recent studies have demonstrated that α oscillations play a causal role in cognition and perception. However, whether and how cognitive or sensory processes modulate various components of the α rhythm is poorly understood. Sensory input and resting states were manipulated in human subjects while electroencephalography (EEG) activity was recorded in three conditions: eyes-open fixating on a visual stimulus, eyes-open without visual input (darkness), and eyes-closed without visual input (darkness). We show that α power and peak frequency increase when visual input is reduced compared to the eyes open, fixating condition. These results …
How To Create And Maintain An Effective Information Architecture And Navigation System For Science Gateway Websites, Noreen Y. Whysel, Omni Marketing Interactive
How To Create And Maintain An Effective Information Architecture And Navigation System For Science Gateway Websites, Noreen Y. Whysel, Omni Marketing Interactive
Publications and Research
Whether you have an existing Science Gateway website or are creating your first one, this hands-on tutorial will show you, step by step, how to create and update gateway websites so that their content is easier to find and easier to use.
As a Science Gateway provides its web-based tools and resources, it is essential that these sites utilize specific usability tests and other research methods to ensure positive and productive experiences with the sites. Successful information architecture (IA), intuitive site navigation, and clear user interfaces (UIs) all rely on knowing where various users expect to find needed information.

Alpha Oscillations And Feedback Processing In Visual Cortex For Conscious Perception, Tony Ro
Alpha Oscillations And Feedback Processing In Visual Cortex For Conscious Perception, Tony Ro
Publications and Research
Variability in perception between individuals may be a consequence of different inherent neural processing speeds. To assess whether alpha oscillations systematically reflect a feedback pacing mechanism for cortical processing during visual perception, comparisons were made between alpha oscillations, visual suppression from TMS, visual evoked responses, and metacontrast masking. Peak alpha oscillation frequencies, measured through scalp EEG recordings, significantly correlated with the optimum latencies for visual suppression from TMS of early visual cortex. Individuals with shorter alpha periods (i.e., higher peak alpha frequencies) processed visual information faster than those with longer alpha periods (i.e., lower peak alpha frequencies). Moreover, peak alpha …
Competitive Frontoparietal Interactions Mediate Implicit Inferences, Martijn E. Wokke, Tony Ro
Competitive Frontoparietal Interactions Mediate Implicit Inferences, Martijn E. Wokke, Tony Ro
Publications and Research
Frequent experience with regularities in our environment allows us to use predictive information to guide our decision process. However, contingencies in our environment are not always explicitly present and sometimes need to be inferred. Heretofore, it remained unknown how predictive information guides decision-making when explicit knowledge is absent and how the brain shapes such implicit inferences. In the present experiment, 17 human participants (9 females) performed a discrimination task in which a target stimulus was preceded by a predictive cue. Critically, participants had no explicit knowledge that some of the cues signaled an upcoming target, allowing us to investigate how …
“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels
“A” For Effort: Rewarding Effortful Retrieval Attempts Improves Learning From General Knowledge Errors In Women, Damon Abraham, Kateri Mcrae, Jennifer A. Mangels
Publications and Research
Previous research has shown that the prospect of attaining a reward can promote task engagement, up-regulate attention toward reward-relevant information, and facilitate enhanced encoding of new information into declarative memory. However, past research on reward-based enhancement of declarative memory has focused primarily on paradigms in which rewards are contingent upon accurate responses. Yet, findings from test-enhanced learning show that making errors can also be useful for learning if those errors represent effortful retrieval attempts and are followed by corrective feedback. Here, we used a challenging general knowledge task to examine the effects of explicitly rewarding retrieval effort, defined as a …
What Influences Language Impairement In Bilingual Aphasia? A Meta-Analytic Review, Ekaterina Kuzmina, Mira Goral, Monica Norvik, Brendan S. Weekes
What Influences Language Impairement In Bilingual Aphasia? A Meta-Analytic Review, Ekaterina Kuzmina, Mira Goral, Monica Norvik, Brendan S. Weekes
Publications and Research
Patterns of language impairment in multilingual speakers with post-stroke aphasia are diverse: in some cases the language deficits are parallel, that is, all languages are impaired relatively equally, whereas in other cases deficits are differential, that is, one language is more impaired than the other(s). This diversity stems from the intricate structure of the multilingual language system, which is shaped by a complex interplay of influencing factors, such as age of language acquisition, frequency of language use, premorbid proficiency, and linguistic similarity between one’s languages. Previous theoretical reviews and empirical studies shed some light on these factors, however no clear …
Cognitive, Behavioral, And Situational Influences On Relapse To Smoking After Group Treatment For Tobacco Dependence, Sara E. Lunden, Jami C. Pittman, Neelam Prashad, Ria Malhotra, Christine Sheffer
Cognitive, Behavioral, And Situational Influences On Relapse To Smoking After Group Treatment For Tobacco Dependence, Sara E. Lunden, Jami C. Pittman, Neelam Prashad, Ria Malhotra, Christine Sheffer
Publications and Research
Socioeconomic disparities in treatment failure rates for evidence-based tobacco dependence treatment are well-established. Adapted cognitive behavioral treatments are extensively tailored to meet the needs of lower socioeconomic status (SES) smokers and dramatically improve early treatment success, but there is little understanding of why treatment failure occurs after a longer period of abstinence than with standard treatment, why early treatment success is not sustained, and why long-term treatment failure rates are no different from standard treatments. We sought to understand the causes of treatment failure from the perspective of diverse participants who relapsed after receiving standard or adapted treatment in a …
Bilingualism, Executive Function, And Beyond: Questions And Insights, Irina A. Sekerina, Lauren Spradlin, Virginia V. Valian
Bilingualism, Executive Function, And Beyond: Questions And Insights, Irina A. Sekerina, Lauren Spradlin, Virginia V. Valian
Publications and Research
The papers in this volume continue the quest to investigate the moderating factors and understand the mechanisms underlying effects (or lack thereof) of bilingualism on cognition in children, adults, and the elderly. They grew out of a 2015 workshop organized by two of us (Irina Sekerina and Virginia Valian) at the Graduate Center of the City University of New York, funded by NSF’s Developmental and Learning Sciences and Linguistics Programs (grant #1451631). The workshop’s goal was to bring together researchers whose fields did not always overlap and who could learn from each other’s insights. In attendance were linguists working on …
